TUMBLING MILL.

Application filed February 25, 1926. Serial No. 90,577.

My invention relates to'tumbling mills,

and ithas for one object the provision of a continuously operating mill wherein the material to be cleaned, as well as the cleaning elements, may be introduced at one end of the mill and positively fed therethrough to the discharge end, the cleaning elements being automatically returned to the entrance end, whereby a continuous supply of clean- Other objects and 'appllcationsof :my invention, as well as details of construction.

and operation, whereby my invention may be practiced, will be apparent more fully here inafter, when taken in connection with the accompanying drawings, wherein Fig. l is a side elevationalvie-w. of a tumbling mill embodying my invention,

Fig. 2 is a horizontal sectional view of the structure! of Fig. 1, the sectional planebemg taken on the'line 22 :of Fig. 1,

Fig. 3 is an end elevational view 'of' the structure of .Fig. 1, looking from the right on the line 4-40f Figi2. V In the illustrated embodiment of my mvention shown in the drawing, a tumblingg' mill'l comprises an inner shellor drum 2, having an inletopening 3 at a"'smallerend 4 for the reception of-castings torbe cleaned and 'adischarge outlet 5 at a larger end 6. Experience has shown that whena shell of such form is filled with material-' to be cleaned, as for example, radiator castings? and cleaning or abrasive, means 8, the movement of the shell causes thecastings 7 and cleaning means 8 to be automatically fed therethrougln v The tapered shell 2 comprises a perforated section 9 atthe smallerend 4 thereof through whichthe cleaningmeans or jacks Sareauto matically fed in manner'that will presently appear; a perforated section 10 adjacent to v the larger end 6; and an intermediate 1111-,

Fig. this a transverse sectiona'l view taken perforate section 11, which constitutes the;

principal abrasive or cleaning chamber. The perforated section 10 comprises a section 12 having relatively tin-e perforations 13 through which the'material that is removed from the castings 7 may pass. Thesection 10 also comprises an adjacent section 14: wherein the perforations 15 are of increased size, so that the smaller of the jacks 8 may pass therethrough, the remaining jacks 8 passing through the larger perforations 16 of a perforatedportion 17 of section 10 which is disposed atthe end of the shell 2. The jacks 8 are thus gradually removed from the shell 2 as they approach the discharge outlet 5 thereof, only the larger of, the jacks reaching the perforated portion 17 of' section 10.

A plurality of longitudinally extending strips 18 may be mounted on the inner side of tapered shell 2, sothat the castings 7 and jacks v8 may be lifted'upon the movement of shell. Such sand as still adheres to the castings 7 as they approach the discharge outlet 5fmay be removed by causing said castingsto be raised to an elevated position and then permitted to fall so as to turn end forend.

, This desired result may be accomplished by a plurality of angularly disposed members'19, a vertical wall 20 of each being positioned as shown in Figs. 1 and '41 so as to exert a lift-- ing' and turning action as the tapered shell 2 rotates. The newpositionassumed by the castings after being actuated by the members 19 is illustrated at 21 in Fig. 2

. In accordance with myiinvention, the jacks 8, which pass through the perforatedsection 17, at the dischargeend 6 of shell 2, are automatically conveyed by means of a conveyor shell or: drum '22 to the perforated section 9, at the entrance end 4 of; the shell 2, where-a by aself-contained,continuously operating tumbling mill maybe had.) To this end, I have so designed the outer conveyor shell 22 that the respective ends'23 and 24 thereof surround the perforated section 17, through which the jacks pass roman shell 2, and the'perforated section -9, through which the endsft and 5 of the inner shell 2 may be rigidly secured to the adjacent ends of the jacks enterthe inner shell2. The respective outer casing 22 by means of annular plates 25. and 26, which also serve to close the ends of an annular chamber 27 that is formed.
